Martin Marietta completed its combination with Lhoist North America on August 21, adding more than 2 billion tons of limestone reserves and positioning itself as the nation’s leading producer of limestone products. The acquisition and other deals have driven record Specialties results and higher aggregate shipments, prompting management to raise full-year revenue guidance while reaffirming adjusted EBITDA guidance. Growth has been accompanied by a $52 million noncash inventory step-up charge, rising organic COGS per ton and persistent energy and diesel cost pressure, and the company expects about 24 months to return to its target investment-grade leverage. Market indicators show modestly increased hedge fund ownership, low short interest, and a forward P/E of 28.09 reflecting elevated growth expectations. » More on finance.yahoo.com
